Here, I will solve an issue which met by a lot of people, confused but don’t know how to do: How to send mail in UTF-8? Here I will tell you how to send an email with not only a UTF-8 subject but also a UTF-8 content. It’s simple. Just read the following code. Quote your subject with '=?UTF-8?B?' and '?='. You may choose to use HTML to edit your email content, just don’t forget to declare UTF-8 character set. That’s all.
